My 199, awarded V1/V3, but in comments said specifically that the condition does not qualify for CRSC. It did not elaborate, might be something similar on yours.
Based on Ron's linked info and your post being V4 - Y I'm making a SWAG that you got severance pay (<30% DoD) and not medical retirement pay because your DoD % was to low.
I'm pretty sure you have to have retirement pay to get CRSC, because it's an offset for pay lost by accepting VA disability. (In these matter i defer to Ron's vast expertise). So following my SWAG with a second one, I'm guessing it was denied because you didn't have a retirement check to offset.

You are absolutely correct.
CRSC replaces some or all of waived retired pay associated with the receipt of VA compensation.
